Google assistant not available on S21?

[Ash25]

Still getting to grips with the new device but can't seem to work out how to get Google assistant to work. Keeps saying not available on this device. I'm assuming this means..... Its not available. (duuuurrrrr) 

This means I can't use the voice function on android auto when connecting my phone to my car. Disappointing. Any fixes or alternatives?

I've got the s21 ultra, and hold the home button and Google assistance appears, and Bixby is holding the power button.

I discovered I had disabled the Google app which is why the assistant app wasn't working. I prefer not to use Google as a search engine so disabled it to save battery.

attention qu'il y a un problème avec les mises à jour, en effet si vous avez (comme moi) transféré depuis un autre samsung avec smart switch, certaines appli ne se mettent pas à jour en automatique, je dois aller les mettre manuellement ce qui pose parfois problème de compatibilité
